A chromosome is an 'X' shaped gene which contains DNA, found inside living cells. Chromosomes are easily seen using a microscope and are normally invisible most of the time (t…his period of time called 'interphase') but become visible when the cell starts to multiply.

The small bodies in the nucleus of a cell that carry the chemical "instructions" for reproduction of the cell. They consist of strands of DNA wrapped in a helix around a c…ore of protein Chromosomes are thread-like structures that are found in the nucleus of a cell.

They carry the tens of thousands of traits that are inside you to make you look like who you are. During sexual reproduction your Parents give you half of each of their Geno…me; which are copies of theirs. Some of the traits may be dominant, which shows [are expressed] over the recessive traits. Chromosomes have genes on them, which are passed down from a parental generation to their progeny.

Chromosomes are the rod-shaped, filamentous bodies present in the nucleus, which become visible during cell division. They are the carriers of the gene or unit of heredity. Ch…romosome are not visible in active nucleus due to their high water content, but are clearly seen during cell division.

The purpose of chromosomes in the nucleus of a cell is to contain genetic information that tells the cell what to do, how to behave etc. Chromosomes also contain the informati…on that determines what you look like; whether you have brown hair, blue eyes etc.
